There has been no flooding in low-lying areas of Brisbane as a result of today's high tide.

The Bureau of Meteorology (BOM) says the Brisbane River peaked at 1.5 metres in the city reaches which is below the level of a regular king tide.

The Brisbane City Council had warned that the release of water from Wivenhoe Dam could cause flooding when combined with this afternoon's high tide.

But the BOM's hydrology expert Peter Baddiley says the threat has passed.

"We see these sorts of high tides," he said.

"They're not unusual even without releases from Wivenhoe so they're not unusually high today."

Sandbagging

Some residents spent the day sandbagging as a precaution, but Brisbane Lord Mayor Campbell Newman says the information council put out was not alarmist.

"I ask someone to show me where it says a wall of water is coming down to engulf the city of Brisbane, run for the hills," he said.

"It doesn't say that - I missed that, I'm sorry."

Seqwater says its release from Wivenhoe is in line with its guidelines.

Unified message

Queensland Premier Anna Bligh says emergency authorities should be giving the public the same message about potential flooding in Brisbane.

She has been running the State from a temporary base at Townsville in north Queensland.

"I do think this is confusing and I think it would be much better for the Brisbane City Council and the Bureau [of Meteorology] and Seqwater to be speaking with one voice," she said.

"When I return to Brisbane one of the things I'll be doing, given we are expected to have a very, very wet summer, is meeting with those agencies and I think we need to put a protocol in place about the advice that's given."

CityCat service

Brisbane CityCat and ferry services are unlikely to resume until tomorrow morning because of debris in the river.

The council says shuttle bus services are operating from several ferry terminals.
